Specification of Letters Patent.

Application filed February 17, 1905. Serial No. 246,082.

T0 at wlwnt it may concern:

Be it known that I, ELLERY M. HOAGLAND, a citizen of the United States,residing at the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Gates, of whichthe following is a specification.

My invention relates to improvements in gates; and it consists in anovel combination and arrangement of parts composing the gate wherebythe latter is so counterbalanced as to move easily at all points betweenfull opening and closing and in means where by the gate maybe unlatchedby the preliminary portion of the opening movement.

My invention comprises details of construction which will be more fullyexplained by reference to the accompanying drawings, in which- Figure 1is a side view of my gate closed. Fig. 3 is Fig. 4 is a modian end viewof same open.

of upper bar,

fied form. Fig. 5 is a view partly broken away.

My invention is especially applicable to gates hinged at one end to apermanent post and adapted to be raised about the hingeoint, while thebars forming the gate are ioldable against each other, so that the gateis reduced to the smallest possible thickness when open and willautomatically extend itself to fill the gate-opening when closed.

A is the post, which is preferably slotted or made double, and the toprail 2 of the gate extends through this post at the height at which thisrail is to stand when the gate is closed.

The gate may either be composed of parallel rails 3, loosely connectedwith the upper rail by vertical bars 4, to which the horizontal railsare loosely pivoted, or there may be a bottom rail connected by verticalbars set near enough together to form the desired gate or obstruction.These vertical bars 4 are loosely pivoted in the top and bottom rail, sothat when the upper bar is turned about its pivot-pin to raise the upperrail into an approximately vertical position the vertical bars will turnso as to lie close together and parallel with each other, while thebottom rail in the same manner closes in toward the top rail, the wholemovement be- 1 parallel ruler,

the opening and closing of a and this effect is produced in eitherconstruction.

The top rail of the gate is extended beyond the pivot-point in thesupporting-post and may carry a counterweight, as at 6. I have hereshown mechanism connecting with this weight so that it is automaticallyslidable upon the rear extension of the top, so that at all pointsbetween opening and closing of the gate itwill be substantiallycounterbalanced.

In order to operate the gate, I may use any of the Well-knowniormseither cranks fulcrumed upon the ground so that the carriagewheelsmay pass over them and connections between these cranks and thegate-actuating mechanism or levers fulcrumed I either near the ground oroverhead and projecting so as to be reached by persons approaching thegate from either side.

The gate may be latched or secured when closed by alongitudinally-slidable latch, as at 7. This latch. may be a shortspringpressed bar adapted to engage with a catch or notch 8 upon theouter post, against which the gate closes, and having a light wireextending along the top bar of the gate to the pivot-post, or the latchmay comprise a rod in like manner extending along the top of the gate. Ashort latch and wire or cord by which the pull may be exerted are verysuitable for the purpose.

The wire or cord 9 has its end contiguous to the pivot-post connected toa bell-crank or equivalent lever 10, which is fulcrumed at its angle,and the other end of the lever is connected with the lever mechanism 11,by which the gate is actuated.

The pull-rods 11 from the actuating-levers connect with one arm of theangular lever 1 1. Another angle of said lever is pivoted to thegate-post, and a third angle is con nected by a rod 12 with a lever-arm10*, which projects from the top bar of the gate and provides leverageto start the gate in its opening and closing. A link 12 connects thelever 1.0 withthe lever 10, and by means of a slot 14 in lever 10 thebell-crank 10 will be first moved to disengage the latches before poweris applied to lever 10 to open or close the gate.

Rods 13 connect with the gate-postA above ing similar to the point atwhich the top rail is pivoted to the post. The ends of these rods arealso connected with the sliding weight 6.

It will be manifest that when the gate is closed and in a horizontalposition the angular direction. of the rods 13 will be such as to pushthe weight outward and away from the post, thus increasing itscounterbalancing effect upon the other end of the gate, and when thegate is raised, so as to be opened, as the extension of the top railbehind the post moves downward the pull upon the weight through the rods13 will draw the weight nearer to the post and reduce itscounterbalance-weight upon the gate. Thus by these or equivalentconnections the gate will always be substantially counterbalanced in anyposition from fully open to fully closed.

The latch may preferably be subjected to a light spring, as at 15, whichwill cause it to engage the catch upon the outer post when the gate isclosed, and the movement of the operating-lever which serves to closethe gate will release the tension or pull upon the latch, so that itwill be in readiness to engage the catch on the post when the gate isclosed.

In order to insure its remaining open until it is desired to have itclosed, a latch 17 is slidably carried upon the rear extension of thegate, so that when the gate has been turned up in its open position thislatch will engage a catch or stop 18. This latch is connected by a wireor cord 19 with the bellcrank lever 10, and when by the movement of thelever 11 the closing of the gate is commenced this latch is firstwithdrawn from its engaging catch, while the same movement places thelatch 7 in position to engage with its catch when the gate is againclosed.

The counterbalance-weight may be adjusted to move more or less byincreasing or decreasing the angle of the rod 13. This is done bynotches or perforations 20 upon the vertical post with which the end ofthe rod may be changed to connect.

By journaling a pulley 21 on the post A above the gate and connecting acord 22 with the gate and with aweight 23, suspended on the oppositeside of the pulley, the gate may be partially counterbalanced, and theweight may be varied to correspond with changes of position of the gateby making the weight in sections. The suspending-cord may pass througheach of the upper sections and be fixed to the lower one. The weightsabove the lower one increase in diameter or are otherwise constructed,so that as they move in guides when the gate first commences to open allthe weights act to counterbalance it and as the gate approaches theperpendicular one or more of the weights will be successively arrestedand supported. The cord sliding through the arrested weight andconnected with the lowermost weight will thus provide for aconstantly-decreasing weight as the gate approaches its open position,and when the gate closes additional weights will be picked up until thegate is fully counterbalanced.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination of a folding panel-gate having its top rail pivoted,an extension of said top rail, a weight slidable upon said extension andconnections between the weight and the pivot-post whereby the weight ismoved away from the post when the gate is closed, and is drawn towardthe post when the gate is opened.

2. The combination of a folding panel-gate, the top bar of which ispivoted in a post and extended beyond said post, guides upon saidextension, a weight slidable in the guides, arms connecting said weightwith a point above the pivot of the bar, operating-levers extending toeither side of the gate, and connections between said levers and thegate.

3. The combination in a folding panel-gate having a top bar pivoted to afixed post and an extension rearwardly of said bar, of guides upon saidextension, a weight slidable in said guides, a connection between saidweight and a fixed point above the pivot-point of the gate, a tiltablelever pivoted upon the gate, a latch adapted to engage with the outerpost, connections between said latch and the tiltable lever,operating-levers extending away from the gate and connections betweensaid levers and the latch-actuating lever.

4. In a vertically tiltable and foldable panel gate, a latchhorizontally movable upon the top rail, a catch in the outer post withwhich the latch is engaged when the gate is closed, a fulcrumed leverwith which the latch is connected, levers and connections by which thegate is moved about its fulcrum, a loose connection between said gatelevers and the latch-lever whereby the latter is moved to disengage thelatch previous to the opening movement of the gate, an extension of thetop rail and a shiftable weight upon the extension actuated by theopening and closing of the gate.

5. In a vertically-tiltable panel-gate having a pivoted top rail with anextension beyond its pivotal point, a weight disposed at the rear of thepivotal point of the top rail and means connected to the weight and bywhich the position of said weight is varied to correspond with thevariations of the weight of the gate, a horizontally-movable latch bywhich the gate is held in a closed position, a second latch on theextension of the top rail and by which the gate is retained in an openposition, a bell-crank lever mounted upon the gate, connections betweenthe lever and the two latches, and other connections between leverwhereby the lever is moved the lever and the gate opening and closingmeans whereby one of the latches is moved to engage and the other todisengage.

6. A vertically-tiltable gate having in combination a gate-post, a toprail ivoted thereto with an extension in rear of t e pivotal point, ahorizontally-movable latch by which the gate is held in a closedposition, a second latch by which the gate is held open, a bell-cranklever between the two latches and connections between the lever and thetwo latches, a movable connection between the gate opening and closingmeans and said to actuate the latches before movement is. communicatedto the gate, and a variable counterbalance movably mounted at the rearof the pivotal point of the top rail and means connecting thiscounterbalance with the post whereby the counterbalance approaches, orrecedes from, the post as the gate is vertically moved.
